I STEAM H EATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 499,231, dated June 13,1893.

Application filed August 13, 1892. Serial :Nm-143,029. (No model.)

.To all whom it may concern.-

Beit known that I, FRITZ KAEFERLE, a subj'ect of the King ofWiirtemburg, and a resident of Hanover, Germany, have invented a new anduseful Improvement in Steam Heating Apparatus, of which' the followingis a full, clear, and exact specification.

In order to regulate accurately and quickly asteam heater, it isnecessary to allow the hot steam free access and in any desiredquantity, and to permit the Water of condensation to I'low oiI as soonas formed without interfering with the entrance of the steam, and at thesame time preventing absorption of the heat by the accumulated water.Iaim in this manner to overcome the shocks so noticeable in steamheaters by providing for the inlet of the steam and exit of the water ofcondensation through the same pipe, but-without the slightestinterference.

In the accompanying drawings; Figure 1 shows a sectional view of part ofa steam heater with my regulating apparatus annexed to it. Fig. 2 is anend View of Fig. 1 partly in section. Fig. 3 is a side elevation of partof a heater similar to Fig. l. Fig. 4 is an end 'view of Fig. 3 with theregulating means in section. Figs. 5 and 6 represent a longitudinal anda vertical section of a regulating apparatus of a modified construction.

a, represents a hollow body placed lengthwise within a casing b whichalso serves to support the heater or as a base therefor. This pipe ortube a is in connection at one end with the steam conducting pipe c andat the other end with the heater D. The hollow body and .the bearingtherefor within the case which can be either of cylindrical or ofconical shape, are provided with two corresponding openi-ngs d and e, ofwhich cl is located on the top and e at the bottom, which openings forma connection between the conducting pipe c and the heater D. Thecase his further provided with a short pipe f which projects into the innerpart of the heater D and is intended to provide a passage for the steamindependent of the exit for the condensed water which flows from "theheater through a passage formed around the pipe f leading to the case band from thence the water of condensation flows through the openinge tothe conducting pipe o, so that a crossing of the hot steam with thecondensed water is prevented and consequently also the vstriking and theshocks in the heating apparatus. If the heater' works always under a lowpressure of steam and the steam penetrates into the heater without muchtension,-

the pipe f can be omitted without affecting the silent operation of theapparatus. If on the contrary the heater works with a high pressure thepipe f must be used, because in that case, the steam which rushes inunder a high tension will try to push back and drag 'along theoutflowing water, and will then occasion the striking and the shocks.

The steam used for the heating of the apparatus D penetrates into thehollow body a through they pipe c and from there into the inner part ofthe heater itself through the top opening d, where it communicates itsheat to the walls of the same. The condensed water gathers in the lowerpart of the heaterD and of thecase b,"passing off through the loweropening e of the body a to the pipe c and thence to' the boiler, or to atank built for that purpose. By turning the hollow body a along itslongitudinal axle, the openings d and c wherewith it is provided comeinto a different position in regard to the corresponding openings in thecase b, vby which the apertures through which the steam passes can bemade larger or smaller in' order to regulate the same. This bringing inmotion of the hollow body can be caused by an endless worm g with ahandle which engages teeth on the periphery of lthe body or. A screw c'in the case b limits the movement of the hollow body a.

In Figs. 5 and 6 a slight change is made over the construction shown inFigs. l to 4. In Figs. 5 and 6 the body extends to the rear of thecasing b and has direct communication with the pipe f and the worm andgear for rotating it are at the extreme end.

In combination with a steam heater, an outlet pipe c, a pipe f, fordelivering the steam to the heater, a revoluble body c ining an openingfor the outiow of said Water, aelrposed between thez inlet pipe c, andpipe Substantially as described.

laving an opening ,for the escape of steam Y f r f to the said pipef,'ti1e said pipe being of FRI FL KAEFERLE' 5 smaller diametex than thesurrounding frame Witnesses:

whereby a passage is left for the escape of FRIEDR. WEILM, the water ofcondensation, said body a, hav- F. R. PRATT.
